PA-PLAYA LA is absolutely unreal for driving. I have done a couple conventions there, I HATE it. I wound up driving almost exclusively on side streets instead of the “freeway” because though it should take longer, those roads continued to move, the freeway was almost always at a stand still. I didn’t use Waze, it was called using your brain, but we have smart phones for that shit now.
As for Apps, Mile IQ is the most useful to me, it records my drives in the background so I don’t have to keep a log and sets it up perfectly for tax reporting.
